The inventor finds that the air inlet end of the existing gas generator is generally connected with the air inlet end through the silicone rubber pipe, and in the operation process of the gas generator, the gas generator vibrates during operation, and the silicone rubber pipe has the risk of falling off due to the change of the temperature of the mixed gas of the gas and the air compressed by the compressor and the pressure of the mixed gas, so that the operation safety of the gas generator is influenced.
In order to solve the above problem, in the embodiment of the present application, the intake pressure at the intake end of the gas generator is acquired at intervals, and the reference pressure corresponding to the intake pressure is acquired; calculating a pressure change rate corresponding to the gas generator based on the air inlet pressure and the reference pressure; and when the pressure change rate is smaller than or equal to a preset threshold value, prompting that the connection part of the gas inlet end of the gas generator and the gas inlet pipe falls off. This application confirms the reason that the inlet pressure of the inlet end of gas generator reduces through the pressure change rate that detects gas generator inlet end, and then can the short-term test gas generator inlet end whether drop with the junction of inlet end to can guarantee gas generator's operation safety.
The following further describes the content of the application by describing the embodiments with reference to the attached drawings.
The embodiment provides a detection method for a gas generator, as shown in fig. 1, the method includes:
s10, intermittently collecting the air inlet pressure of the air inlet end of the gas generator, and acquiring the reference pressure corresponding to the air inlet pressure.
Specifically, the intake pressure is the gas pressure at the intake end of the gas generator, that is, the intake pressure is the gas pressure of the gas flowing into the gas generator. The interval refers to the collection of the air inlet pressure of the air inlet end of the gas generator at preset time intervals, or the collection of the air inlet pressure of the air inlet end of the gas generator according to a preset interval time sequence. For example, the intake pressure at the intake end of the gas generator is collected once every 3 seconds, or the intake pressure at the intake end of the gas generator is collected at changing intervals of 3 seconds, 4 seconds, 5 seconds, and the like.
In an implementation manner of this embodiment, the gas generator may be used in a gas power generation system as shown in fig. 2, a joint between an air inlet end and an air inlet end of the gas generator is connected with a gas through a silicone rubber pipe, the gas passes through a gas flowmeter, passes through an electromagnetic valve, is mixed with air, enters a compressor for compression, and the compressed mixed gas enters the gas generator, is cooled by intercooling water, and then enters an air cylinder. Wherein, the gas flowmeter can detect the temperature, the pressure and the flow of the gas. Therefore, the inlet pressure can be obtained by reading the pressure value collected by the gas flowmeter, that is, the inlet end of the gas generator is provided with the gas flowmeter, and the inlet pressure at the inlet end of the gas generator is collected at intervals, specifically: and reading the pressure value of the gas collected by the gas flowmeter at intervals to obtain the gas inlet pressure of the gas inlet end of the gas generator.
The reference pressure may be a preset standard pressure, or may be an intake pressure collected before the intake pressure at the intake end of the gas generator. In one implementation, the reference pressure and the intake pressure are acquired at two adjacent acquisition times, and the second acquisition time corresponding to the reference pressure is before the second acquisition time corresponding to the intake pressure. It is understood that the reference pressure and the intake air pressure are acquired by two adjacent acquisitions, and the second acquisition time corresponding to the reference pressure is located before the second acquisition time corresponding to the intake air pressure. For example, the intake pressure is collected at the fourth collection, and the reference pressure is collected at the third collection.
In addition, when the reference pressure and the intake pressure are acquired by two adjacent acquisition times, after the first acquisition time corresponding to the intake pressure and the second acquisition time corresponding to the reference pressure are acquired, the stored data set of the reference pressure and the second acquisition time can be deleted, so that the occupation of the storage space can be reduced on the basis of ensuring that the second acquisition time corresponding to the reference pressure and the reference pressure can be acquired.
And S20, calculating the pressure change rate corresponding to the gas generator based on the air inlet pressure and the reference pressure.
Specifically, the pressure change rate is used for reflecting the proportional relation between the pressure change value and the reference pressure, and the change reason causing the pressure change at the air inlet end of the gas generator is determined through the pressure change rate so as to perform response operation on the gas generator. In one implementation manner of this embodiment, the calculating a pressure change rate corresponding to the gas generator based on the intake pressure and the reference pressure specifically includes: calculating a pressure difference between the reference pressure and the intake pressure; calculating a ratio of the pressure difference to the reference pressureAnd obtaining the corresponding pressure change rate of the gas generator. That is, the calculation formula of the pressure change rate may be: (P)t1-Pt2)/Pt1Wherein P ist1Is a reference pressure, Pt2As intake pressure, t1Second acquisition time, t, for reference pressure2Is the first acquisition time of the intake air pressure.
And S30, when the pressure change rate is smaller than or equal to a preset threshold value, prompting that the connection part of the gas inlet end of the gas generator and the gas inlet pipe falls off.
Specifically, the preset threshold is preset and is a basis for determining that the air pressure is changed, wherein when the pressure change rate is smaller than or equal to the preset threshold, it indicates that the air pressure is changed due to the fact that the connection between the air inlet end of the gas generator and the air inlet pipe is dropped, and conversely, when the pressure change rate is larger than the preset threshold, it indicates that the air pressure is changed due to the fact that the gas generator stops supplying gas. Based on the method, after the pressure change rate is obtained, the pressure change rate is compared with a preset threshold value to determine the reason causing the air pressure to change, and the gas generator is controlled to execute corresponding operation according to the reason causing the air pressure to change. In a specific implementation manner, the value range of the preset threshold may be 0.003 to 0.005, for example, the preset threshold is 0.004. Of course, in practical application, the air pressure at the air supply end of the gas generator may change, so that the air inlet pressure P may occurt2Greater than the reference pressure Pt1When the pressure change rate is negative, the gas generator is judged to be in a normal gas supply state, and the gas generator is kept to normally work.
In one implementation mode, when the pressure change rate is smaller than or equal to a preset threshold value, it is indicated that the air pressure change is caused by the falling of the connection part of the air inlet end and the air inlet pipe of the gas generator, and at the moment, the gas generator has an operation risk, so that the gas generator can be controlled to stop working; and when the pressure change rate is larger than the preset threshold value, the air pressure change is caused by the air stopping of the gas generator, and the gas generator is in safe operation at the moment, so that the gas generator can be controlled to work according to normal working procedures.
By way of example: let t1Time t and2the time is two continuous acquisition times, t1The intake pressure collected at any moment is the reference pressure Pt1，t2The intake pressure collected at the moment is the intake pressure P at the current momentt2(ii) a Then the rate of change of pressure is (P)t1-Pt2)/Pt1If the preset chamber threshold is 0.4%, then (P)t1-Pt2)/Pt1>0.4%, it means that the air pressure is reduced due to air cut-off, and the gas generator is controlled to work according to the normal working procedure, otherwise, if (P)t1-Pt2)/Pt1<0.4%, and (P)t1-Pt2)/Pt1>And 0, otherwise, controlling the gas generator to stop due to the reduction of air pressure caused by the falling of the connection part of the gas inlet end and the gas inlet pipe of the gas generator.
In summary, the embodiment provides a detection method for a gas generator, and the method includes acquiring air inlet pressure at an air inlet end of the gas generator at intervals, and acquiring reference pressure corresponding to the air inlet pressure; calculating a pressure change rate corresponding to the gas generator based on the air inlet pressure and the reference pressure; and when the pressure change rate is smaller than or equal to a preset threshold value, prompting that the connection part of the gas inlet end of the gas generator and the gas inlet pipe falls off. This application confirms the reason that the inlet pressure of the inlet end of gas generator reduces through the pressure rate of change who detects gas generator inlet end, and then can the short-term test gas generator inlet end whether drops with the junction of inlet end to can guarantee gas generator's operation safety.
